Expression 3,
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.
Answer: (x^2)/16 + (y^2)/25 = 1
Step-by-step explanation:
According to the problem we can figure out that the center of the ellipse is (0,0).
Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.
If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2
We get b^2 is 16
Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.
Polygons are easy to classify p
Answer:
66 cm
Step-by-step explanation:
Diameter (d) = 21 cm

Answer:
The equation would be L = 2d + 52
Solution:
when d = 31 days
L = 2(31) + 52
L = 62 + 52
L = 114 miles
The total length of the road after the crew has worked 31 days is 114 miles.
